Fig. XII is an end view of the cord-knotter, showingcord-gripper and cordcutter; Fig. XIII is a rear perspective view, partsbeing cutaway to show the tilting graincarrying fingers, cam-tracks,dischargingchain with tilting-fingers, and the grainretaining fingersthat hold the gavel until bound. Fig. XIV is an end view of a cam-track,showing fingers with devices for breaking the track to tilt thefingerssooner when the needle is 50 down. Fig. XV is a perspective view of my'B by a clutcl1,h, is a counter-shaft, c, havtilting-fingers as attachedto an open link chain. Fig. XVI is a modification of my device fortilting the reel-bats. Fig. XVII is a top view of the machine. Fig.XVIII is a detail perspective view of the reelsupporting device.

A represents a platform; B, the endless carrier, supported'on rollers B;O, the cutter-bar; O, a divider, and D the driving-wheel, all of whichmay be of any suitable construction.

Intermediate of the carrier and d riving-wheel is the usualbinding-table, A, having needleslot A, and to which is secured at thefront end the standard A formed with an arm, A provided with a head, A.

Straddling the driving-wheel are supports A for a platform, A, providedwith a seat, A for the driver of the machine.

Connected to the shaft 0 of the inner roller ing a sprocket-wheel, 6.

WV is a sprocket-wheel secured to a shaft, WV, by which the pitman C ofthe cutter-bar is reciprocated.

d is the butter-shaft, having a sprocketwheel, d.

I is the needle-shaft, extending through the rear end of the arm A ofthe standard A having a loose sprocket-wheel, I.

K is a short shaft operated from the driv- 8o ing-wheel and providedwith a sprocket-wheel, K. These sprocket-wheels e, d, .V, and I arerotated by a chain or band, H, common to all driven from wheel K.

A is a chain or band tightener having a pulley, A", which bears thereon.The short shaft K carries at its inner end a small bevel gear-wheel, K,with which meshes. a large bevel gear-wheel, F, on a shaft, G, whichcarries at its inner end a pinion, G, rotated by 0 the internal gear, E,of the driving-wheel.

Secured to the needle-shaft If within the arm overthe standard is abevel gear-wheel, I", meshing with another bevel gear-wheel, I on avertical shaft, I, journaled within the standard, and having at itslower end a cam, 73, and disk 1 )rovided with an eccentric wristpin, i.The cam i vibrates a lever, ac, connected with the clutch h of the shaft0.

To the wrist-pin z" is secured a similar pitman, Q, to that shown in myapplication No. 171,809, for reciprocating the slide U of the knottingmechanism.

T is the front ejector-shaft, journaled in the arm A and bracket T onthe head A and extending therethrongh. To the outer end of this shaft issecured a cam, is, and gear-wheel M, having a delay-shoe, N, fittingagainst an auxiliary rim, P, on a mutilated gear-wheel, L, securedrigidly to the needle-shaft I, and whose teeth mesh with the teeth ofthe gearwheel M. The butter-shaft d is mounted in a short standard, d atits front end and in the bracket T at its rear end.

Hinged to the butter-shaft on each side of the bracket are the pairedtrip-arms X, eX- tending beneath the front ejectorshaft, having pairedcam-tracks V formed thereon, the arms X supported on a spring-bar, b, bymeans of a cross-bar, b.

At the front ends of the bnttershaft and at the rear ends of thecam-tracks on short shafts, respectively, and between the camtracks, aremounted sprocket-wheels Z), carrying the endless chains b, having hingedfingers h.

On the shaft (2 near the standard is hinged the butter, supported at itsrear end between spring-bearings 0, extending from the butter-shaft tothe front ejector-shaft. The butter consists of paired cam-tracks,sprocketwheels, endless chains, and fingers similar to those with whichthe triparms are provided. In rear of, parallel with, and journaled inthe same bracket as the front ejector-shaft is the rear ejector-shaft,Y. Supported on these two shafts are a series of paired cam-tracks, U,similar to those of the trip-arms and butter. The shaftYis provided withretaining-fingersa.

A is the needle-bar of the binder, secured, as usual, at the end of itsshaft 1.

In Fig. XIV, a is a spring on the head of the standard, which bears uponone end of a vibrating lever, c, which is pivoted to the head at d, andis supported beneath the spring on a pin, a, projecting from theneedle-bar through a slot, at, in the head. The other end of the leversupports a rod, 6, connected to the armf of a hinged track-piece, fclosing a break, 9, in the bottom of the cam-track V.

The form of tilting-finger h, I prefer to use with the cam-tracks isshown in Fig. XV, pivoted to the chains and having rollers 7c, whichtravel on the cam-tracks.

Hinged to an arm, b secured to the stand ard is a block, S, extendingbeneath the rear end of the needle-shaft, having a cam-piece, R, securedobliquely thereon and supported by links I) on one end of the lever 1),whose other end is connected to the vertical rod 12. On thesprocket-wheel I is secured a disk, X, having a perforation to receive apin, O, projecting from the upper end of a collar, W, pivoted to theneedle-shaft and provided with another pin, Q, at the lower end, onwhich the cam-piece R is caused to bear.

Secured to the inner side of the driving wheel is a gearwheel, Z,meshing with a pinion, Z, on a short shaft, Z having a sprocket-wheel,p, and clutch-collar o,w1th the movable member of which engages theinner end of a swinging lever, a, which is secured at its outer end toan arm, in, on a hinged post, Z, caused to bear upon the cam on thefront ejector-shaft by means of a spring, Z.

At the rear end of the platform is a short shaft, Z, carrying asprocket-wheel, p, in line with the sprocket wheel 19. Around thesesprocket-wheels p p travels the endless discharging-chain Z, havingfingers h". On the underside of this table are secured the brackets A Bfor supporting the knotter.

A is the knotter, working in front of the bracket and having the shankA, operating the hinged lip 13. Jonrnaled to the shank is a roller, 0.

Secured to a bracket, 1 is a spring-arm, A bearing on the roller to drawthe piston inward and close the lip.

A is another arm, against which the inner end of the piston abuts.

The spring-arm A is provided with acam, D, on which the roller 0 bearsto throw the piston out.

The knotter is provided with a pinion, E, engaged by a rack, N, on theslide U, as in my application No. 171,809.

G are spring gripper-plates, between which a circular plate or gripper,F, operates, having notches forming projections for seizing andretaining the portion of the cordlaid in the usual V-shaped opening orrecess, F, between the lip-guide and gripper-plates on one hand and theopposing bracket, A, on the other hand.

The gripper is secured to a shaft, F provided with a ratchet-wheel, H,engaged by a spring or pawl, H, to prevent the shaft from turningbackward. Secured to the rear end of this shaft is a clutch havinghalves K K One member, K, of the clutch has pin L and longitudinal slotconnection L with the shaft,

so as to turn the latter, while at the same time it is permitted toslide thereon. The other member, K, of the clutch is loose on the shaft,and is provided with radial teeth L, engaging a rack, K, on the slide U.Aspring, M, compels the clutch-teeth to engage, so that when the slideis moved in one direction the clutchhalves will turn together, and whenthe slide moves in the opposite direction the teeth of the loose memberwill slip on the teeth of the other half.

P is the hook for placing the cord in the parts of the knotter, as in'myprevious application No. 171,809, being provided with a pinion, Q, onits shaft Q", engaged by the rack (not shown) on the slide U.

The bracket 13* is formed with an inclined lipguide, S, providing astationary cutter.

Hinged at R to the bracket A, in which the grippershaft is journaled atits outer end, is a moving cutter, R, held in normal position against astop, It", by means of a stud, It, and spring V, and elevated by meansof a springcam, T 011 the slide U,brought in contact with the heel T andadjustable by means of a set-screw, T.

1 is the reelshaft, journaled in the arms 2 2 of a bail, 3, hinged by ashaft, 4, to another bail, 5, whose arms 6 are hinged to a shaft, 7,secured to the platform A.

On the shafts 1, 4, and 7, respectively, are sprocket-wheels 8, 9, and10.

On the side of the sprocket-wheels 9 and 10 are secured additionalsproeket-wheels,11 and 12, respectively.

13 isa sprocket-wheel on the shaft G.

14, 15, and 16 are chains which connect, respectively,the sprocketwheels 8 and 9. 11 and 12, and 10 and 13. The arm 2 of the forward bailextends rearwardl y and is provided with a handle, 17, within easy reachof the operator, and a spring-catch,18, engaging the teeth 19 of alever, 20, hinged to the frame, and I whose spring-latch 21 engages theteeth 22 of a rack-segment, 23. This construction permits the reel to beraised or lowered on the shaft 4 and carried forward or rearward by thelever 20.

On the arm 2 is hinged a lever, 24, connected to a sliding sleeve, 25,on the reel-shaft.

26 is the reel,whose arms '0 are secured to a fixed sleeve, 28, at theouter end and to a bevel gear-wheel, r, at the inner end, having asleeve, 29, loose on the shaft.

Journaled to the reel-shaft is a short shaft, 80, having a small bevelgear-wheel, a, mesh ing with the bevel gear wheel r, and apinion,t,engagin g a rack, 5, extending through a curved slot, 9", in thegear-wheel r from a rod, 31, secured to the sliding sleeve 25. Thisconstruction permits the adjustment of the bats 82 according to theposition of the grain.

In Fig. XVI, I show a modification in the means for adjusting the bats,consisting of a sliding sleeve, 33, on the reel-shaft, connected to therod 31, having a spiral slot, 84, in which plays a pin, 35, within thesleeve 29 of the bevel gear-wheel r.

The operation of the sever al parts of my improvements is as follows:The grain, falling onto the apron B, is carried to the transferring andtilting fingers h, traveling 011 the camtracks V, by which it is movedforward and formed into a gavel against the retaining-fingers a andunder the trip-arms X, as explained in my application No. 171,809. Asthe needle descends and the bundleis bound the cog-teeth on wheel L meshwith the teeth of the wheel M, operating the shaft T, causing thetiltingfingers on camtrack U to discharge the sheaf onto chain Z, andcausing the retaining-fingers a to revolve out of the road of the sheafand to come into position again to stop theinflowthe end of thelever cand the arm 0' is raised, lifting the track-piecef and opening the break7' in the bottom of the cam-track V, causing the fingers h to tiltbackward and run on the upper part cf the rest of the track to the endto, instead of crowding the straw against the needle. As the needleascends again the pin a raises the free end of the lever c and closesthe break 9' in the track V again. As the sheaf accumulates under thepresser-bars X they are gradually raised up, raising the vertical bar band the front end of lever I), and lowering the piece S until the properamount of straw has accumulated, when the track R on piece S falls belowthe end of pin Q, and the spring 0 throws the pin 0 into a hole 1n wheelX, and the needleshaft is revolved. As the needle ascends the block S israised by the weight of the triparms after the bundle is ejected, andthe oblique track R switches the arm WV back into normal posit-ionagain. As the ejecting-fingers and cam-track U eject the sheaf onto thechain Z, the cam 75 operates through post Z and arm at, the lever 12throwing the clutch 0 into connection, operating the chain Z andejecting the sheaf into the stubble. As the needle descends with thecord a rack on piece V operates pinion Q, causing the eordguide P totake the cord and carry it across the path of the knotter. The notchedrotary gripper F presses thecord between the spring gripper plates orjaws G and carries the cord down the inclined lip-guide or knife S intothe jaws of the knotter-hook. These plates G and the gripper F hold thecord so tightly that the knotter in drawing the twine necessary to formthe loop in its revolution must draw it from around the bundle insteadof from the needle. This assists to tighten the cord around the sheaf.The traveling rack N turns the knotter, twisting the cord around thehead of the k notter. The roller 0 comes against the cam D*, opening thejaw B of the knotter, and as the knotter revolves the cord is takenbetween the jaws, which are then closed on the same by the roller 0*slipping off the cam D, and the further revolution of the knotter drawsthe loop over the part of the cord held between the jaws, forming theknot, when the cord, which is held by the cord gripper F between thegripper-plates G, is cut by the knife R, which is operated by the cam Ton the slide U.

While the knot is being tied, thecam t on the upright shaft in the headof my machine operates the device 00, to disengage the clutch h on shaft0 and stop the grain-apron from feeding the grain in.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is

1. The combination of a binding-table, a support thereover,a frontejector-shaft, a rear ejector-shaft, belts extending from shaft to shaftfor ejecting the bundle built thereunder, means for intermittentlyoperating the shafts, and the retaining-fingers a, secured to the rearejector-shaft, against which the bundle is built, substantially asdescribed.
